Specification of Letters Patent.

Patented'Aug. 29, 1916.

Application filed April 29, 1913. Serial No. 764,372.

l To all whom, t may concern Be it known that I, JOHN S. NICHOLS, citizen of the United States, residing at Batesville, in the county of Independence and State of Arkansas, have invented certain new and useful Improvements in Cultivators, of which the following is a specilication, reference being had therein to the accompanying drawing.

This invention relates to cultivators and has for its principal obj ect the production of means for regulating the angle of the cutting means.

Another object of this invention is the production of a bar which may be formed from a single strip of material.

Vith these and other objects in View this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

` 37 adapted to be positioned between plates of a clip and held in place by means of a pivoted bolt. This plow beam 40 is twisted intermediate its length as shown at 41 to form the fiat supporting face 42, and is then again twisted as shown at 43 to form the handle section 44 which is provided with an enlarged head 45 having the curved slot 46. A bracing bar 47 has its front end provided with an eye through which a pivot bolt passes to pivotally mount the bracing bar. This bracing bar comprises the front and rear sections, which sections are adjustably secured together by the bolts 50 which pass through the openings 51 formed in the two sections. By having these bracing bars adjustable it will be seen that the end of the bracket may be regulated, thus regulating the angle of the digging means.

A bracket is attached to the vertical bar 60 from which there extend the upper and lower strips 54 which are provided with alined openings. Vertical arms 57 extend above and below the strips 54 and are provided with openings through which bolts 59 may be passed to secure the bracket to the vertical bar 60, to which the digging means are attached. The rear end of the bracing bar is passed through the strips 54 and pivotally held in place by the bolts 61, and the flattened portion 42 of the plow beam is passed between the free end portions of the strips 54 and pivotally held in place by a bolt which passes through a selected set of openings. By this construction the distance between the plow beam and the bracing bar may be regulated and by adjusting the length of the bracing bar the angle of the bracket may also be regulated. The handle 63 is secured to the plow beam by the bolts 64 and 65, which pass through the slot 46 and opening 66.

From the foregoing description it will be seen that a cultlvator has been produced wherein the angle of the digging means may be adjusted as desired. It will also be seen that a very simple and eilicient plow beam has been produced which is formed from a single bar of material.

Having thus described the invention what is claimed as new, is

A beam for a plow formed from a single bar of material, comprising a body being rectangular in cross-section, said body tapering toward its forward ends, an eye formed Vintegral upon said tapering end, said body bent intermediate its ends to form a horizontally extending Hat supporting face, whereby a digging means may be supported upon said face, said body then being twisted to extend in a plane at right angles to said at face and extending slightly upwardly forming a stub handle grip portion whereby a handle may be attached thereto. In testimony whereof I hereunto aiiix my signature in presence of two witnesses.
